Question

python使用oracle查询数据库，查询语句中使用变量值

代码如下：
import cx_Oracle
def getdata(Item):
conn=cx_Oracle.connect('p00292','pan00292','hsmmdb-rac-scan.uniview.com:1521/HSMM')
cursor= conn.cursor()
cursor.execute('select * from INV.MTL_ITEM_REVISIONS where ROW_ID= %s'% (Item,))
fir=cursor.fetchone()
print fir
getdata('AAAdjoAAzAAABL7AAB')

运行python后显示的错误消息如下：
D:\Python27\python.exe D:/python自动化测试/ceshi1.py
Traceback (most recent call last):
File "D:/python自动化测试/ceshi1.py", line 8, in <module>
getdata('AAAdjoAAzAAABL7AAB')
File "D:/python自动化测试/ceshi1.py", line 5, in getdata
cursor.execute('select * from INV.MTL_ITEM_REVISIONS where ROW_ID= %s'% (Item,))
cx_Oracle.DatabaseError: ORA-00904: "AAADJOAAZAAABL7AAB": invalid identifier
请大神们赐教

Answer 1

cursor.execute('select * from INV.MTL_ITEM_REVISIONS where ROW_ID= %s'% (Item,))

换为：
qry_sql = "select * from INV.MTL_ITEM_REVISIONS where ROW_ID= '%s'" % Item
cursor.execute(qry_sql)

Answer 2

ROWID值的%s 需要单引号

Answer 3

getdata("'AAAdjoAAzAAABL7AAB'")
